How we pick alternatives
We start from real engineering teams, not search volume. Every alternative on this list comes from change-log data, public migration posts, and our own survey of engineering managers — not just "tools that share keywords with Convex." If nobody is actually replacing Convex with a tool, it does not appear here, even if it shows up on other ranking sites.
We list real tradeoffs, not pros-and-cons theater. Every cons section is a real reason your team will hit friction with that tool — pricing jumps after a usage threshold, ecosystem gaps, breaking changes between versions, missing integrations. We do not pad cons with vague complaints to make pros look better.
Pricing reflects what you will actually pay. "Starts at" numbers are the realistic entry point for a small production team — not the marketing-only free tier. We update these prices when vendors change them, with the last-updated date stamped at the top of this page.
No pay-to-play ranking. DevVersus earns affiliate commission on some links — those are tagged with the disclosure above. Affiliate status does not change ranking order. Tools with no affiliate program outrank ones we earn from when they fit the use case better.

Why do developers switch from Convex?＋

For a side-by-side breakdown, see our /compare/convex-vs-supabase-realtime page.
Should I migrate from Convex to one of these alternatives?＋
Migration is rarely worth it for cost alone — you should switch only when your current tool blocks a workflow, scales poorly, or is being deprecated. If Convex is meeting your needs, the lock-in cost (re-training the team, rewriting integrations, retesting) often outweighs the savings. Use this page to identify candidates, then run a 1-2 week proof-of-concept before committing.
